	SurvivorCore — Survival Stats admin plugin (main).

	A toolbar button toggles a dock widget that edits the survival-stats `SurvivalStatsConfig`
	instance through StatAdmin — the deltas-only, LOCKED model: it writes only fields the owner
	changes from the engine default, removes them on reset, and can NEVER write the engine-owned
	semantics (Invert / DangerHigh). Edits are wrapped in ChangeHistoryService recordings so each
	is a single undo step. All real logic lives in StatAdmin (testable); the form in StatAdminUi.

	First slice of the Builder / Admin plugin (issue #11).
